Classify a Triangle Given Coordinate Points | Part 2

The video tutorial explains how to classify triangles by examining their angles and sides. It introduces the use of the distance formula to verify triangle types, such as isosceles and right triangles. The tutorial also covers how to use slopes to confirm right angles in triangles. The importance of plotting points and using mathematical formulas for verification is emphasized, with a focus on understanding triangle properties.

What is the first step in identifying the type of triangle when given three coordinate points?

• Calculate the area of the triangle.

• Plot the points on a graph.

• Assume the triangle is equilateral.

• Directly apply the distance formula.

When plotting points to classify a triangle, what is a common assumption made before verification?

• The triangle is equilateral.

• The triangle is scalene.

• The triangle is always right-angled.

• The triangle is isosceles.

Which formula is used to verify the equality of side lengths in a triangle?

• Pythagorean theorem

• Slope formula

• Area formula

• Distance formula

What is the result of using the distance formula on two points with coordinates (3,1) and (1,5)?

• Square root of 25

• Square root of 10

• Square root of 20

• Square root of 5

How can you verify that a triangle is a right triangle using slopes?

• Check if the slopes of two sides are equal.

• Check if the slopes of all sides are zero.

• Check if the slopes of all sides are undefined.

• Check if the slopes of two sides are opposite reciprocals.

What does a zero slope indicate about a line?

• The line is vertical.

• The line is horizontal.

• The line is undefined.

• The line is diagonal.

What is the significance of an undefined slope in the context of triangle verification?

• It indicates a parallel line.

• It indicates a horizontal line.

• It indicates a vertical line.

• It indicates a diagonal line.
